Abstract: A disposable face mask is made up of molded fibrous sheet material which is formed to define a generally cup-shaped main body having two spaced, generally parallel, integral, interior nose portions filter-seals which are strategically located to engage opposed sides of the nose of the wearer. The mask body also desirably has an elongated, integral interior chin portion filter-seal which is positioned to engage the face underneath the wearer's chin. The nose and chin filter-seals cooperate to prevent passage of contaminated air beneath the peripheral edge of the mask and the user's face. The elongated nose filter-seals are especially effective in preventing passage of contaminated air along paths of travel which extend from the nose bridge encompassing part of the mask to the user's nostrils of mouth. The same is true of the chin filter-seal. The nose and chin portions preferably interconnect to form a continuous filter-seal around the periphery of the mask.

Abstract: A disposable protective cover for face-engaging respirators, or the like, which is particularly useful in a contaminated environment in preventing particulate buildup on the respirator. For example, in painting operations the cover protects the respirator from paint buildup and contamination, preserving the respirator from undue wear and reducing frequent cleaning and maintenance of the respirator. The cover presents a thin, flexible body configured to generally conform to the shape of the outer surface of the respirator. The body has an opening to provide access to the respirator intake and a cuplike section to provide a loose fit of the cover around the respirator exhalation valve to allow unrestricted breathing. The covers hereof present structure for quick attachment or detachment of the covers from the respirator. The exact structural features of the covers are adapted to accommodate different types of respirators, such as full face or half-face masks, and external air source or filter type masks.
